A. Location-based services for wireless assets or RFID tags

B. FTP over implicit TLS/SSL

C. Data connection with frequent roaming

D. On-demand video streaming over wireless

Question 2

When performing an indoor predictive site survey to make the WLAN planning and design
cycle more efficient, what is a best practice for configuration of the simulated APs in the predictive modeling software?

A. Always use the default 2.2 dBi omnidirectional antenna patterns for simulated APs.

B. All simulated APs should be set to 20 MHz channels only.

C. If dynamic RRM will be used, AP transmit power should be set to an estimated average level of the expected client devices, such as 25 mW.

D. Defining custom AP and antenna patterns will yield more accurate prediction data than the pre-configured vendor AP/antenna combinations.

Question 3

Given: The 802.11n APs you have selected for your public access deployment support many of the PHY and MAC enhancements offered by the 802.11n standard. The AP is single-band (2.4 GHz) and only allows 20 MHz channels. The WLAN radio in the AP is a 3x3 802.11n chip that supports two spatial streams.
What is the maximum MCS rate that could be supported by this AP?

A. 144 Mbps

B. 150 Mbps

C. 300 Mbps

D. 54 Mbps

E. 108 Mbps

F. 65 Mbps

A. Calculate RF path loss in free space

B. Calculate earth bulge to determine minimum antenna height

C. Calculate the loss experienced between the intentional radiator and antenna

D. Calculate the minimum voltage requirements for lightning suppression systems

Question 6

Given: Use the exhibit as a reference. ABC Company has a WLAN controller with 10 controller-based APs; the Voice SSID is configured for centralized data forwarding. Each AP is connected to an access port on a layer-2 Ethernet switch. Each layer-2 switch is uplinked to a single layer-3 core Ethernet switch. The WLAN controller is connected directly to the layer-3 core Ethernet switch. Layer-3 tunnels are created between all controller-based APs and the WLAN controller. A voice server is connected to the layer-3 Ethernet switch.

When a voice-enabled QoS STA sends an IP data packet to a voice server in this scenario, the DSCP value carried in the STA's IP data packet gets mapped to what and by which device?

A. The DSCP value is mapped to an IEEE 802.1p (802.1D-2004) UP value by the access point.

B. The DSCP value is mapped to the DSCP value in the encapsulating IP header by the layer-3 switch.

C. The DSCP value is mapped to an IEEE 802.1Q priority tag value by the WLAN controller.

D. The DSCP value is mapped to the VLAN ID by the layer-2 Ethernet switch.

E. The DSCP value is mapped to an IEEE 802.1Q VLAN tag by the access point.
